Specification of Letters Patent.

Patented Feb. 28, I911.

Application filed July 21, 1910. Serial No. 573,035.

To all whom it may concern:

Be it known that I, NnMnsIUs NIELSEN, a citizen of the United States,residing at Oloverport, in the county of Breckinridge and State ofKentucky, have invented a new and useful Wrench, of which the followingis a specification.

It is the object of the present invention to provide an improvedconstruction of wrench and the invention aims more particularly toprovide an improved pipe and rod wrench which may be manipulated to morefirmly grip the elements to be turned than is possible with wrenches ofthis general class now in use.

In the ordinary wrench for turning pipes and rods, such as the wellknown alligator type of Wrench, considerable lateral pressure must beexerted against the pipe or rod being turned in order to cause the jawsof the wrench to grip the pipe with a suflicient degree of friction toturn the same. The present invention therefore aims to provide a wrenchin which such force will not be required to be exerted and which maywith the exertion of less force, be made to more firmly grip the pipe orrod.

Briefly stated, the wrench 0f the present invention consists essentiallyof two alligator wrenches having jaws pivoted together so that thewrenches may be swung upon their pivot to bring their jaws intocoiiperative relation and their handles in juxtaposition so as to becapable of being readily grasped in the hand for the purpose of closingthe jaws about the element to be turned.

With the above and other objects in view, the invention consists in thegeneral construction and arrangement of parts shown in the accompanyingdrawings, in which,

Figure 1 is a perspective view of the wrench open. Fig. 2 is a side Viewof the wrench closed. Fig. 3 is a sectional view on the line 33 of Fig.2.

In the drawings, the wrench is illustrated as embodying two members oneof which is indicated in general by the reference character A and theother by the reference character B. The member A comprises a handle 5and a head 6 having a jaw 7 and a jaw 8, this head being V-shaped or inother words in the form of an ordinary alligator wrench head and theinner edge of the jaw 8 of the head is toothed or serrated as indicatedby the numeral 9.

The member B of the wrench comprises a handle indicated by the numeral10 and formed with a head similar in general detail to the head 6 of themember A and indicated by the numeral 11. This head 11 instead ofcomprising a pair of jaws, consists of two pairs of jaws one pair beingindicated by the numeral 12 and the other pair being indicated by thenumeral 13, the pair 12 corresponding in general to the jaw 7 of thehead 6 and the pair 13 with the jaw 8 gf this head, in every detailexcept in num- In assembling the members of the wrench, the extremity ofthe jaw 8 is inserted between the ends of the jaws 12 and a pivot pin 14is secured through the jaws mentioned thereby pivotally connecting thesemembers in the manner illustrated in the figures of the drawings. Theinner edges of the two jaws 13 of the heads 11 are toothed or serratedas at 15 in the same manner as is the inner edge of the jaw 8 of thehead 6.

In Fig. 1 of the drawings, the wrench is shown open whereas in Fig. 2 itis shown closed and it will be readily understood that when in openedposition, it is so disposed against the pipe or rod to be turned thatthe said pipe or rod will be received between the jaws 12 and 13 of thehead 11 or the jaws 7 and 8 of the head 6 and the other member is thenswung upon the pivot 14: to the closed position shown in Fig. 2 of thedrawings whereupon ,the handles 5 and 10 will be brought injuxtaposition and may be grasped in one hand and the jaws caused tofirmly grip the said pipe or rod.

It will of course be understood in connection with the foregoingdescription of the invention that the inner edges of all of the jaws ofthe two heads may be toothed or serrated or all may be plain or they maybe otherwise selectively toothed or serrated. It will further beunderstood that the heads may be of a shape other than \l-shape and thatnumerous slight modifications may be made without departing from thespirit of the invention as defined in the appended claims.

What is claimed is z- 1. In a wrench, a pair of handles, a twojawed headrigid with each handle, and a pivot connecting one jaw of each head.

2. In a wrench, a member comprising a two-jawed head, a handle rigidtherewith, the member having one edge of one jaw of its head serrated,and a member comprisserrated, the jaws of the two pairs'being ing handlehaving a head rigid therewith In testimony that I claim the foregoingand comprising two pairs of jaws, corre as my .own, I have heretoaifixed my signa- 10 sponding' jaws of each head having one edge ture inthe presence of two witnesses.
